Abstract
The invention discloses an imitative digital printing method. The method comprises the steps of color separation, stretching, blue light plate making, tintering, squeegeeing, ageing, water washing and drying. The color separation step comprises the following processes: inputting a required printing pattern into a computer, processing the pattern by combining photoshop and Jinchang printing and dyeing color separation software to obtain monochromatic images of various colors in the pattern, and increasing several or all of orange, green, yellow, indigo and purple on the basis of red, yellow, blue and black colors; and mutually staggering 25-30DEG or 30-65DEG between adjacent color screening angles. The technology combining a traditional printing technique with a computer image processing technique makes the color separation tend reasonability, enables the color space to be larger than a traditional four-color forme space, increases the detail color of the pattern, increases the stereo perception of the pattern, has a low production cost, has a substantially better effect than common printing, and realizes a digital printing approaching effect in visual sensation.
Description
Technical field
The invention belongs to dyeing or the stamp field of textiles, relate in particular to a kind of method of imitative digit printing.
Background technology
At present, in dyeing there is traditional screen printing and digit printing in printing in textiles technical elements.The technique that tradition screen printing Technology Need is retouched the series of complexes such as original text, plate-making, engraving, impressing pattern is limited by chromatography simultaneously, but the speed of traditional screen printing technology stamp is fast, and with low cost during stamp in enormous quantities; Along with scientific and technological development, Digital Dyeing is very ripe idol technically, Digital Dyeing, without plate-making, is drawn a design convenient, is not subject to the restriction of pattern chromatography, the fineness of color reaches 1080dpi, even higher, can print off very meticulous picture, but Digital Dyeing is slower several times, simultaneously higher as the ink price of main consumptive material, causing stamp in enormous quantities is high expensive.
Summary of the invention
The object of the invention is: make screen printing can approach the effect of digit printing on pattern and color, give full play to the advantage of screen printing technology on stamp speed and cost, Printing of high quality and at a reasonable price is provided.
In order to achieve the above object, the invention provides following technical scheme: a kind of imitative digital printing method, comprise color separation, the net that stretches tight, blue light plate-making, tinting paste, scrape, evaporate, washing and baking step;
A, described color separation step are that the style of required stamp is input in computer, in conjunction with photoshop and Jinchang calico color separation software, style is processed, requirement according to cover chromatic number, the color separation method of the spatial relationship of the feature of employing based on decalcomania and color and image, obtain versicolor monochrome image in pattern, color is divided into 4 ~ 8 and adds n color, wherein 4 ~ 8 refer to and on the basis of red, yellow, blue, black four kinds of colors, increase any several or whole in orange, green, indigo, four kinds of colors of purple; N refers to the spot color quantity of increase; Adjacent color screen angle mutually staggers between 25 ° ~ 30 ° or between 30 ° ~ 65 °, being shaped as of site is square; Site number and angle organically combine, and by the adjustment of n kind spot color and angle of halftone screen line, compensate inaccessiable style color after the folded look of color selected in 8 kinds of color separations;
B, the described net step that stretches tight are when using plain net, adopt 135 ~ 180 object half tones;
C, described blue light plate-making step are that output file carries out photosensitive lithographic to blue light platemaking machine;
D, described tinting paste step are to select dyestuff according to the compatibility of dyestuff, then according to color separation original text, modulate a small amount of corresponding mill base, with the mill base modulating, make sample; Ready-made sample is fed back to color separation software and again make correction, according to revised result, modulate required mill base;
E, the described step that scrapes are with the mill base modulating and the half tone of making, textiles to be scraped.
Described mill base is REACTIVE DYES mill base further, and wherein mill base comprises the raw material of following percentage: the former paste 60% of sodium alginate; Urea 10%; Sodium bicarbonate 3%; Anti-paint salt 1%; Surplus is water.
Evaporating further temperature is 103 degrees Celsius to 105 degrees Celsius; The time of evaporating is 8 minutes.
During described washing process, add soaping agent further, soaping agent content is 3-5g/L.
The invention has the beneficial effects as follows: traditional printing technique is combined with computer image processing technology, simultaneously by image with different image processing softwares in conjunction with processing, make color separation more rational, use 8+n look forme, color space is larger than four traditional look forme spaces, the effect that can obviously improve group, increases the details color of pattern, and pattern stereoscopic impression increases; Its production cost is significantly less than digit printing, and due to not limiting of color tricks, according to the independent assortment that needs of actual pattern color, its effect is better than common stamp greatly, approaches digit printing on visual experience.
The specific embodiment
Below by embodiment, technical scheme of the present invention is described further.
